Definitions

  • This invention relates to the field of acoustic devices and more particularly to the field of acoustic coupling seals for use with a sound transmitting tube which is directed into the outer ear.
  • Certain forms of hearing aids, dictating machines, tape players, and telephones presently being used today no longer use the ear mold or ear tip which forms a tight acoustic seal with the ear canal thus excluding all outside sounds. This has generally been the case because of the physical arrangement of the components within the hearing aid producing feedback which is highly undesirable for the wearer.
  • the acoustic tube may be introduced into the ear canal with no mold or other tip closing the space between the ear canal and the outer configuration of the tube. With this type of hearing loss, the hearing aid amplifies the higher pitched sounds which are then carried to the ear drum through the tube and the lower ranges are permitted to reach the ear drum directly.
  • the present invention is directed to an ear tip which also forms an acoustic connection or coupling to carry out the provisions of permitting the higher pitched sounds to be amplified through a hearing aid or other amplifier and permitting the lower pitched and normal sounds to be received directly into the ear.
  • the ear tip is formed of a soft plastic material and openings are formed around the outer portion of the tube which extends into the tip member much like the openings between the spokes of a wheel. It has also been found that it is desirable in some cases to be able to regulate the amplitude and control the frequency of the sound received in this manner and a disc is also provided which has apertures formed therein which may be used for increasing or reducing the amplitude of the lower pitched and other normal sounds received directly.
  • FIG. 1 is a perspective view of the acoustic seal used with a sound tube
  • FIG. 2 is an elevational side view of the acoustic seal used with a sound tube
  • FIG. 3 is an elevational end view of the acoustic seal used with a sound tube as fitted in the ear.
  • an acoustic coupler 10 which has an elongated and tapered bulb-like hollow housing 11 which is of a proper dimension to be fitted in the outer ear of the wearer. It has been found that the outer diameter is generally between the dimensions of 0.265 inches and 0.335 inches depending upon the size of the ear canal of the wearer.
  • the general length of housing 11 is approximately one-half to three-fourths of an inch with the thickness of the outer shell being approximately 1/32 to 3/32 of an inch.
  • the tapered housing 11 has an end 2 and an inner opening 14 which communicates with an opening 13 formed in 12.
  • Portions of the outer housng 11 are exposed providing a plurality of openings 15 which, because of their symmetrical relationship, form a plurality of ribs 16 which are formed substantially parallel to the longitudinal axis of member 11.
  • the ribs 16 may also be formed like screw threads if desirable, as long as adequate openings are formed between them.
  • a flexible conduit 20 has one end adapted to be fitted to a sound transmitting device such as a hearing aid or other devices described earlier and has a second end 21 which extends through opening 14 in the hollow housing into opening 13.
  • a circular disc 22 may be used, and when used, is secured in the larger end of housing 11 through the use of an annular groove which releasably secures disc 22 in a radial manner at a normal open position of housing 11.
  • Disc 22 has a central opening 23 for receiving flexible conduit 20 and also includes a plurality of apertures 24 which are formed by a plurality of intermediate members 25 like spokes or round openings, etc. in a wheel.
  • the openings in disc 22 may be circular in nature and disc 22 may also be made in two cooperating parts to adjust the size of apertures 24.
  • the total area of the plurality of apertures 24 are substantially larger than central opening 23.
